Transmissive 8.8 cm (3.5-Type, Wide) ACX391AKB 920k-Dot Color LCD Panel Features the VSPEC IIITM Wide Viewing Angle LCD Mode
The ACX391AKB is a built-in driver diagonal 8.8 cm active matrix panel that uses lowtemperature polycrystalline silicon transistors. This panel features ultrahigh resolution (213 ppi) and provides a detailed and smooth display. It also provides improved visibility from all viewpoints by adopting VSPEC IIITM, a new wide viewing angle LCD mode. This panel allows direct connection to the DSP using a direct interface method and achieves a significant reduction in the number of peripheral components. ■ Direct interface method allows direct connection to the DSP ■ VSPEC III (wide viewing angle technology) achieves the wide viewing angle of 160° in the up/ down and right/left directions (CR 100:1) ■ Number of display dots: 920k dots in an 8.8 cm (3.5-type, Wide) stripe arrangement panel ■ Horizontal resolution: 360 TV lines ■ Optical transmittance: 6.0% ■ New LCD mode adopted Contrast: 800:1 ■ Wide color gamut: NTSC 65% ■ Up/down and/or right/left inverse display function ■ Sub-bright adjustment function

Direct Interface (8-bit RGB Serial)
The driver IC is mounted on the panel itself, and the interface is 8-bit digital and achieves the expression of 16.77 million colors. Furthermore, NVM is also included and the Vcom adjustment value is written prior to shipment. Thus there is no need for Vcom adjustment in end products.
High Contrast
The ACX391AKB achieves the high contrast of 800:1 by adopting the VSPEC III TM technology. In conjunction with the increased viewing angle characteristics, this creates a high picture quality panel.
Increased Resolution
This panel features ultrahigh resolution (213 ppi) and provides a detailed and smooth display. The number of dots displayed is 640H × 3 × 480V = 921,600 dots.
